FIELD OF THE INVENTION

The present invention relates to hair or skin conditioning compositionscomprising: (a) a thickening polymer system; (b) a surfactant systemselected from the group consisting of cationic surfactant, nonionicsurfactant, and mixtures thereof; (c) a hydrophobically modified amidosilicone copolyol; and (d) an aqueous carrier; wherein the compositionhas a transmittance of 25% or more and/or wherein the composition has aviscosity of from about 1,000 cps to about 50,000 cps and Shear ThinningIndex of 30 or more. The compositions are especially suitable for haircare products such as hair conditioning products for rinse-off/leave-onuse.

BACKGROUND OF THE INVENTION

A variety of conditioning compositions such as hair conditioningcompositions and skin conditioning compositions have been used for avariety of substrates such as hair and skin. A common method ofproviding conditioning benefits is through the use of conditioningagents such as cationic surfactants and polymers, high melting pointfatty compounds, low melting point oils, silicone compounds, andmixtures thereof. Most of these conditioning agents are known to providevarious conditioning benefits. For example, some cationic surfactants,when used together with some high melting point fatty compounds, arebelieved to form a gel matrix which has a suitable rheology forconditioning compositions and which is suitable for providing a varietyof conditioning benefits, especially when used for hair care products,such as slippery feel, softness and reduced tangling on wet hair andsoftness and moisturized feel on the dry hair.

Most of the above conditioning agents are also known to make thecomposition opaque. Thus, there is a need for conditioning compositionshaving a clear product appearance i.e., transparent or translucentproduct appearance.

Additionally, there exists a need for achieving a suitable rheology forconditioning compositions by other methods than forming the above gelmatrix, while maintaining the conditioning benefits of the gel matrix.

Furthermore, most of the above conditioning agents are also known toweigh down the hair when these conditioning agents are included in haircare compositions. For consumers who desire maintaining or increasinghair volume such as consumers having fine hair, weighing down the hairis not desirable. Thus, there is a need for hair conditioningcompositions which do not weigh down the hair while providingconditioning benefits.

Based on the foregoing, there remains a need for conditioningcompositions which provide a clear product appearance. There alsoremains a need for such conditioning compositions which provide asuitable rheology. There is also a need for such conditioningcompositions which are suitable for providing further benefits such assufficient conditioning benefits and/or not weighing down the hair,while providing a clear product appearance and/or a suitable rheology.

None of the existing art provides all of the advantages and benefits ofthe present invention.

For the silicone deposition measurement, 2 gram hair switches are used.The hair switches are prepared by following steps:

-   -   (a) Providing five cycles of shampoo/conditioning treatments to        the hair switch, each cycle of shampoo/conditioning treatment        consisting of following steps:        -   (a-1) Applying a shampoo at a level of 0.2 cc and lathering            the hair switch; and rinsing the hair switch;        -   (a-2) Applying a shampoo again at a level of 0.2 cc and            lathering the hair switch; and rinsing the hair switch; and        -   (a-3) Then providing conditioner treatment to the hair            switch, the conditioner treatment consisting of applying a            conditioner at a level of 0.2 cc and treating the hair            switch; and rinsing the hair switch; and    -   (b) Then drying the hair switch.        The hair switch is ready for the measurement of its silicone        deposition amount.        (ii) Silicone Deposition Measurement

The deposited silicone on the hair switch is extracted in an appropriatesolvent. The extracts are then introduced into an atomicabsorption/emission detector instrument and measured at the appropriatewavelength. The absorbance/emission value returned by the instrument isthen converted to actual concentration (ppm) of silicone compounddeposited on the hair through an external calibration curve obtainedwith known weights of a well characterized standard of the siliconecompound under study.
